Abstract: In a slant type headlamp unit for motor vehicles, the reflector has as inner reflecting surface a reflecting area taking the form of a part of a paraboloid of revolution and a light-diverging reflecting area which diverges in the hori­zontal plane, and reflects in the vertical plane the rays of light incident from a lamp bulb in directions substantially parallel with the optical axis. The center of the filament of the lamp bulb is disposed nearly parallelly with the optical axis of the reflector and as spaced slightly frontwardly from the focus of the paraboloid of revolution. A front lens is disposed as slanted with respect to said optical axis, covering the front opening of said reflector and having provided on the inner surface by a plurality of prism areas which refract the rays of light emitted from said lamp bulb and reflected at said reflector, thereby forming horizontally elongated illumination patterns and slant illumination patterns frontwardly. 
     There is formed a finite prism area as positioned above the prism areas of said front lens which forms said slanted illumination pattern and upon which the rays of light reflected at said light-diverging reflecting area are incident being formed as horizontally extended near the horizontal line passing by the intersection with said optical axis to diverge said incident rays of light substantially within the horizontal plane in which said horizontal line lies. Thus, the rays of light reflected at said light-diverging reflecting area form on the road surface an illumination pattern within profile line of   the horizontally elongated illumination pattern in which the luminance is relatively high, thereby providing a luminous intensity distribution pattern which has no bent portion but a sufficiently large spread.

Abstract: A hand held applicator for applying ultrasound power to treat human tissue, includes a transducer (1) having excitation electrodes. A power amplifier (13) responds to an oscillating signal from a variable frequency oscillator (23) to supply electrical power to the transducer (1) via a connection to the excitation electrodes. The transducer (1) and the power amplifier (13) have a power-conversion-­efficiency characteristic that is a function of the frequency of the oscillating signal and the acoustic load on the transducer (1). The frequency of the oscillating signal is controlled by a sampler (5) having a timer for defining alternating sample and hold timing intervals and means for producing a frequency-control signal having a magnitude that varies during each sample interval and that remains essentially constant during each hold interval. The means for producing the frequency-control signal includes a peak-detector operative during each sample interval for setting the magnitude of the frequency-­control signal so that throughout the ensuing hold interval the transducer and the power amplifier operate with essentially peak-power-conversion efficiency.

IPC: B65D43/08
Filed: 1989-04-11
Abstract: A closure 9 for the open mouth 2 of a container includes a main body 8 and sealing means which extends around the periphery of the main body. The sealing means has a sealing edge 17 which is adapted to engage a sealing surface formed on the container, and a resiliently flexible web 16 which connects the sealing edge to the main body. The web is movable between a relaxed condition (Figure 1), in which the diameter of the sealing edge 17 is at a maximum, and a sealing condition (Figure 13), in which the diameter of the sealing edge 17 is less than maximum. When the closure operatively closes the opening 2 in the container the web 16 is moved to the sealing condition, and the resilience of the web material serves to press the sealing edge 17 against the sealing surface 1. Preferably the web 16 in its relaxed condition has a frusto-conical form which diverges upwardly and the sealing edge 17 is formed on the upper and outer edge of the web 16.

Abstract: An active matrix type display device has a plurality of scanning lines (Y1, ... Yn), a plurality of signal lines (X1, ... Xm), and pixels (10, 30, 40, 50, 60) disposed at inter-sections of the scanning lines and the signal lines for providing a display. Each pixel is driven by way of a respective plurality of thin film transistors (1, 2, 23, 24, 31, 32, 33, 41, 42, 51, 52) which are connected to an associated pixel electrode (P).
